Padres Claim Mark Hamburger Off Waivers

The Padres have claimed right-hander Mark Hamburger off waivers from the Rangers and optioned him to Triple-A, the team announced. Jeremy Hermida was transferred to the 60-day DL to clear a 40-man roster spot.

Hamburger, 25, had been designated for assignment late last week to clear a spot on the roster for Roy Oswalt. He appeared in five games for Texas last year and has spent this season at Triple-A, where he has a 6.55 ERA with 7.3 K/9 and 4.2 BB/9 in 45 1/3 innings.
